Stack 8

Number placement

Numbered tiles fall into an 8×8 board, and no number may repeat in a row or column: a repeat turns to stone. Fill a row or a column to clear it, and don't let a column reach the top. Any score is a link a friend can play on the same tiles.

Rules

Tiles fall from the top. Tap a column to drop the tile there.

No repeats. A number can't appear twice in the same row or column. Drop it where its number already is and it turns to stone.
Fill a row or a column to clear it.
Don't let a column reach the top.
